AFE boards for Fiber Tracker

1. AFE Prototype test results

Plot of VLPC gains for each track/PS detector
Plot of one of the best AFE channels
Plot of an average AFE channel
Plot of one of the worst AFE channels (data of 3/12/01)

p.1, p.2, p.3, p.4, p.5 of plots shown by Paul Rubinov on 4/10 of smoothed average signals from LED runs on Bd. 1. Every 4th channel is open to light. Some are with 100 pF and some with 470 pF input to SIFT.

Directory containing pe fit plots shown by T. Nunnemann 4/10/01 and description of conditions. (Updated by TN on 4/17/01)


2. Simulations of CFT performance with predicted AFE (VLPC, fiber etc.) performance.

Alan Bross simulation of Trigger efficiency 3/13/01 for 8 layers out of 8; realistic gains, yields from cosmic ray tests, measured waveguide attenuations, AFE pe resolution, thresholds smeared by 10%, and estimated radiation damage. The upper limit to the efficiency is set by the measured number of dead channels. (If dead channels were set ON, the upper limits would approach 1 at low dose and threshold. (see also d0server4.fnal.gov/users/grannis/bross.ps )

Response spreadsheet for CPS with AFE8 (4/10/01 shows thresholds, dynamic range, counts/MIP etc. for a proposed input cap. on SIFT, for nominal, 30% high or low VLPC gain.

Response spreadsheet for FPS with AFE8 (5/28/01 shows thresholds, dynamic range, counts/MIP etc. for a proposed input cap. on SIFT, for nominal, 30% high or low VLPC gain.

Alan Bross simulation of Trigger efficiency 4/11/01 for 8 layers out of 8; realistic gains, yields from cosmic ray tests, measured waveguide attenuations, AFE pe resolution, thresholds smeared as from preliminary data by Paul Rubinov tests at +/- 2fC. Dead channel effects not included.
